LATEX COMPOSITIONS Russian patent published in 2014 - IPC C08L21/02 C08F236/04 C08F236/12 D21H19/44 

FIELD: chemistry.

SUBSTANCE: invention relates to latex compositions, which are applied in coatings for paper. A latex binding agent for coating of pigmented paper contains particles of emulsion copolymer, which contains (i) from 15 to 35 wt % of repeated links, obtained by acrylonitrile polymerisation; (ii) from 25 to 65 wt % of repeated links obtained by polymerisation of conjugated diene monomer, and (iii) from 5 to 55 wt % of repeated links, obtained by polymerisation of alkenyl aromatic monomer, counted per the total weight of the repeated links in a particle.

EFFECT: invention makes it possible to provide better balance of paper coating properties.
